[0007]

When connecting a terminal to the battery post, the terminal to which the terminal cover is fixed is fitted to the battery post, and a jig is inserted from the operation opening. And tighten the nut. Then, the terminal is fixed to the battery post, and the seal portion is in close contact with the outer surface of the battery to seal the gap between the two. Thereafter, when the cap is fitted into the operation opening, the inside of the terminal cover becomes waterproof. Further, the conductor is surrounded by the conductor covering portion that is continuous with the terminal covering portion while maintaining a watertight state, and thus is in a waterproof state. That is, water infiltration into the inside of the cover is reliably prevented.

<Invention of Claim 2> Most of the conductor of the conductor is waterproofed by resin coating, and the exposed end of the conductor is waterproofed by the conductor covering portion, so that the conductor extends over its entire length. It is completely waterproof throughout. <Invention of Claim 3> Since the terminal cover portion and the terminal are integrated by molding, there is no possibility that both of them are displaced or detached. <Invention of Claim 4> Since the terminal cover portion and the conductor cover portion are integrated, the number of assembly steps can be reduced as compared with the case where both cover portions are separate parts.

<Invention of claim 5> Since the cap is made of a hard resin, the cap is excellent in detachability as compared with the case where the cap is made of the same rubber as the terminal cover. Further, when operating the nut, the cap is removed from the operation opening of the terminal cover, but since the removed cap is connected to the terminal cover by the connecting means, the cap is prevented from being lost.
